Built from solid carbide, it delivers the rigidity and heat resistance needed for demanding production environments. The 140-degree drill point angle promotes self-centering and reduces thrust when entering steel and cast iron. At 0.2008 inches (5.10 mm) in diameter, the bit features a spiral flute with R-thinned web and tapered web configuration for improved chip evacuation and reduced walk. A straight-cylindrical shank with a 6.00 mm diameter seats securely in standard drill chucks and collet holders. The screw machine length format keeps the setup compact and maximizes rigidity at the spindle.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for use in CNC machining centers, drill presses, and screw machines operating on steel, alloy steel, and cast iron workpieces. The 3xD flute-to-diameter ratio suits through-hole and blind-hole drilling in production shop environments. The coated finish extends tool life in high-cycle applications where uncoated carbide would wear prematurely. It is a single-piece, individually packaged unit suited for toolroom restocking or direct line-side use. Machinists and CNC operators working on ferrous parts at moderate-to-high feed rates will find the HP243 series a reliable workhorse drill.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior rigidity and heat resistance over HSS alternatives\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces entry thrust and promotes self-centering\u003c\/li\u003e\n  \u003cli\u003eR-thinned, tapered web configuration improves chip flow and lowers cutting forces\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in continuous ferrous machining applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eScrew machine length format maximizes setup rigidity in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces.

Seat the shank fully and evenly in the collet or chuck before tightening to the tool-holding system manufacturer's specification. Use cutting fluid or coolant appropriate for the workpiece material to manage heat buildup, as this bit does not support through-coolant delivery. Inspect the cutting edges and web for chipping before each use — carbide is brittle and a visibly damaged edge should be replaced rather than reground without proper carbide grinding equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2008 inches (5.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP243\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.046 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP243-2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747361653042,"sku":"HP243-2008","price":69.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0352a38908315ea382cc54e4f57d087d.jpg?v=1788879068","url":"https:\/\/voomisupply.com\/products\/osg-hp243-2008-screw-machine-drill-bit-0-2008-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
